One cold March day, Donna asked her father if she could go for a bike ride. The snow had melted and she was eager to go, as she hadn’t ridden her bike since the previous September. Her father replied that she could go, but that he suspected her tires would probably need some extra air. Why might he say this?

- Imagine a sinking ship with 15 people. There are two lifeboats. One lifeboat can fit 9 people and has relatively few supplies, while the other lifeboat can fit 5 people and has ample supplies. Obviously, this makes it such that there is more demand than there are supplies. Imagine that among the passengers on the ship are the following: A 70-year-old cancer patient A 40-year-old obese man with Type 2 diabetes A 20-year-old heroin addict A 30-year-old HIV positive pregnant woman with a 5-year-old child Imagine that all the other passengers on the sinking ship are otherwise relatively young and healthy. How would you answer the following questions? Would a lottery be an ethically acceptable way of determining access to resources? Why or why not? Would it be ethical to try to accommodate all 15 passengers, or would it be ethical to exclude one or more passengers from access to the lifeboats?
